No, the wetting and drying of the clay soil causes the initial cracks. After these have developed, tree roots will grow into the cracks for moisture.

YES. Tree roots over time can grow under any type of concrete and cause it to crack and lift. If this happens to your border simply pull back the mulch on the inside and pull up the sod on the outside, cut the root on both sides and slide it out from under the border. Your border should fall back into place, and you have restored the look of your edging without replacing it.

Most people know that tree roots stabilize a tree. However, that is only part of their job. Most people don't realize that roots absorb oxygen out of the soil. Tree roots absorb air, water and nutrients such as nitrogen, potassium and phosphorus from the soil then convey these elements to the rest of the tree. All of these are essential for the trees growth and overall health. Tree roots also store starches that are produced during the growing season.

It is very unusual for roots to physically break drains and associated pipe work. However, tree roots are opportunistic and if an old pipe with poor joints is leaking into the surrounding soil this will attract the roots that may then exploit the existing weakness. Then, when repairs are required, a proliferation of tree roots often leads to the blame being placed with a nearby tree.

Build decking or benching around trees, to relieve pressure on the roots. Install other plants around the base of the tree to divert traffic. Put in more trees and spread out the love!

The growth characteristics of many species is to develop surface roots. Silver maples are one example. Many times, surface roots occur when the tree roots are looking for water, the soil is too hard, or the soil is saturated with water. Surface roots can impact sidewalks and driveways.

Generally, tree roots get into sewer lines because they are old and leaking and need to be replaced or repaired. It is rare that tree roots will crush a sewer line. If this occurs, please call the Urban Forest Section to have someone inspect the damage.

Tree roots can normally grow to that of two and one-half times the height of the tree. The area under the canopy of the tree is commonly referred to as the critical root zone. The amount of critical root zone lost is directly related to the amount of die-back in the crown of the tree. In an oak tree, if more than 30 percent of the critical root zone is lost, the tree will die. However, soft wood trees, such as box elder, can tolerate far more root disturbance.

Crack is the street name given to the freebase form of cocaine that has been processed from the powdered cocaine hydrochloride form to a smokable substance. The term "crack" refers to the crackling sound heard when the mixture is smoked. Crack cocaine is processed with ammonia or sodium bicarbonate (baking soda) and water, and heated to remove the hydrochloride. Because crack is smoked, the user experiences a high in less than 10 seconds.

Roots grow toward water vapor or moisture, by a continuous process (hydrotropism) occurring at the very end of the root. The root grows one cell at a time enabling it to enter the small cracks and joints, which may be present in your pipe. After a root enters a pipe, it divides hundreds of times to form a large mass of tender root ends. This root mass will accumulate a thick coating of grease which will collect up on the root mass until a blockage occurs.

No. In six years of controlled use, there has been no indication of damage caused from the spike or cross member entering the root ball. Any piercing will, at worst, cause the roots to grow around the impediment.

Tree roots are opportunistic. While they will not crack a sound sewer service or water line, they will exploit cracks or failures in the lines. The best defense against having tree roots in lines is to make sure that your lines are in good condition and that they're not cracked. If you suspect that tree roots are growing into your sewer line, you can have the roots cut out using a process called "rodding".

Local hardware stores have a chemical for removing tree roots. This will kill the roots that are in the service line.

In general, palm tree roots are no bigger than your finger and do not swell up like oak or pine tree roots, therefore they will not push up on your concrete, etc… and break it.

If the foundation of a house has experienced abnormal differential settlement that is adversely affecting the performance of the structure, the HUD agency will not guarantee a loan for the property unless it has been repaired in accordance with a design developed by a qualified Professional Engineer who will oversee the implementation of the repair.

Tree roots do not cause drains or sewer pipes to break, but they will invade and clog drains that have pre-existing cracks and resultant leakage. Drains are usually six to eight feet below ground level, while tree roots grow almost exclusively in the upper two feet of soil, because they not only need nutrients, but also oxygen to survive.

Tree roots will certainly contribute to sidewalk failure, but they are not the initial cause of heaving. There are a number of factors that contribute to sidewalk failure: the method of sidewalk construction, type of soil under and surrounding the sidewalk, proximity of the sidewalk to the tree's buttress roots, and others. There are several things that can be done to repair the sidewalk and maintain the health of the tree.

If someone were to crack a code he could 'subsequently' read which transactions have been carried out. 'Subsequently' because the hacker needs a certain amount of time to crack a code. He is not able to divert funds because the transaction will have been completed long ago by the time the hacker has cracked the code. In addition, each time the customer logs on a different code is used.

No! Whilst many “ home doctors” may tell you they do, there is absolutely no truth to this. Corns and callous generally occur due to friction and do not grow from roots. See our common conditions section for a full explanation.
